  • Thermal management system vehicle and method for operating two cooling circuits of a thermal management system
  • the invention relates to a thermal management system for use in a vehicle.
  • the invention also relates to a vehicle with such a thermal management system.
  • the invention also relates to a method for operating two cooling circuits of such a thermal management system.
  • a vehicle is to be understood as any type of vehicle which has at least one first cooling circuit for temperature control of a battery and at least one second cooling circuit for temperature control of an electric motor and power electronics.

  • the multi-way valve assumes an intermediate position in which the coolant flows of the two cooling circuits mix with one another as needed (needs-based mixing mode).
  • the third valve position can be set from a plurality of possible intermediate positions.
  • the individual intermediate positions can be set steplessly (or discontinuously) or steplessly (or continuously). Continuous adjustment favors the temperature control of both the electric motor cooling circuit and the battery cooling circuit.

  • the CPU is designed to process commands that are implemented as a program stored in a memory system, to acquire input signals from the data bus and to issue output signals to the data bus.
  • the storage system can have various storage media in the form of magnetic, solid-state and other non-volatile media, on which a corresponding computer program for carrying out the method and the advantageous embodiments is stored.
  • the program can be designed in such a way that it embodies or is capable of executing the methods described here, so that the CPU can execute the steps of such methods and thus control the thermal management system in question
